if a+b+c=9 and ab+bc+ca-26 find a²+b²+c²?
Answer:
we have :
(a+b+c)² = a² + b² + c² + 2(ab+bc+ca)
a+b+c= 9
and
ab+bc+ca = 26
Substituting the values in the above formula,
We get,
9² = a² + b² + c² + 2×26
81 = (a² +b² +c²) + 52
(a² +b²+c²) = 81-52
(a²+ b² + c²) = 29 is a required answer.

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(10, 10) = 10. It is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 10 × 10 = 100. In the following intermediate step, cancel by a common factor of 2 gives 3/5. In other words - nine tenths minus three tenths is three fifths.

Mr. Thompson earns $ 11.52 per hour. Last week he worked 37 hours how much F.I.C.A tax did he have to pay at 7.65%?
Answer:
$32.61
Step-by-step explanation:
First, we multiply the amount he earns per hour by the amount of hours he worked. $11.52 * 37 = $426.24. Then, we figure out what 7.65% of $426.24 is, which we can do by multiplying 426.24 by 0.0765. This gives us $32.60736, but since there is no form of US money that is worth less than 1 cent, we round to the nearest cent and get $32.61.

c) The height of each cylinder in a set of food-storage containers is 30 cm.
The radius of the largest container is 10 cm.
The volume of the smallest container is one-third the volume of the largest container.
The volume of the middle-sized container is two-thirds the volume of the largest
container. What is the volume of each container?
Answer:
Volume of smallest container = 3141.6 cm³
Volume of middle sized container = 6283.2 cm³
Volume of largest container = 9424.8 cm³
Step-by-step explanation:
The formula to find the volume of a cylinder = πr²h
The height of each cylinder in a set of food-storage containers is 30 cm.
The radius of the largest container is 10 cm.
Step 1
We can find the volume of the largest cylinder
= r = 10cm
h = 30cm
Volume of largest cylinder = π × 10² × 30
= 9424.8 cm³
Step 2
We find the volume of the smallest container
We are told in the question:
The volume of the smallest container is one-third the volume of the largest container.
Hence
Volume of Smallest container = 1/3 (9424.8 cm³)
= 3141.6 cm³
Step 3
The volume of the middle-sized container is two-thirds the volume of the largest container.
Hence,
Volume of the middle sized container =
2/3 (9424.8 cm³)
= 6283.2 cm³
Therefore, the volume of each container is
Volume of smallest container = 3141.6 cm³
Volume of middle sized container = 6283.2 cm³
Volume of largest container = 9424.8 cm³

The features are given as follows:
Initial value, when x = 0, of y = 1000, representing the y-intercept.Rate of change of 2 for each period of 0.3 units.The domain of the function is the set that composes all input values of the function, and as the exponential function does not have any restrictions such as a fraction or an even root, it is composed by all real values.
However, the relevant domain is x ≥ 0, as the number of days does not assume negative values.
The range is the set containing all output values of the exponential function. As the initial value of the exponential function is of 1000 and the function is increasing, the range is y ≥ 1000.

The matrix that is represented by the system of equations is:

Option C is the correct answer.
What is a matrix?A matrix is a set of numbers arranged in rows and columns such that it forms a rectangular array.
We have,
Here, the coefficient matrix is the matrix on the left-hand side, the variable matrix is the column matrix containing the variables x and y, and the constant matrix is the column matrix on the right-hand side containing the constants 12 and 15.
To solve the system of equations, we can use matrix operations to transform the coefficient matrix into the identity matrix, while performing the same row operations on the variable matrix and the constant matrix.
Once we have transformed the coefficient matrix into the identity matrix, the variable matrix will be transformed into the solution vector containing the values of the variables x and y that satisfy the system of equations.
Thus,
